Kinetica; An Excel program to Stimulate or Analyze Kinetic DataLeonel Vera, Pedro Ortega, Miguel GuzmánThe Excel spreadsheet Kinetica both simulates and analyzes kinetic data for simple rate equations of the form: - d[A]/dt = k [A]^n Instructors or students can generate simulated kinetic data using parameters they specify, or using parameters randomized by Kinetica. The data set that is generated may then be exported for use in exercises, homework, and exams, or may be analyzed directly within Kinetica. A kinetics data set may also be imported from an external source into Kinetica for analysis.

An Excel Program to Study First-Order KineticsKen MuranakaUser data can be analyzed to determine what parameter values of the first order rate expression give the closest fit, or data can be generated using user-input values of the rate parameters and random noise levels. Statistical characterizations such as confidence limits and variance are calculated.

Mechanism-Based Kinetics SimulatorRobert M. HansonSimulate the kinetics of a reaction based on its mechanism using JavaScript. The idea is to write a mechanism and, based on that, follow the course of concentrations or rates of change in concentration of reactants, catalysts, intermediates, and products over time.

Connected ChemistryMike StieffConnected Chemistry, a novel learning environment for teaching chemistry, is appropriate for use in both high school and undergraduate chemistry classrooms. Connected Chemistry comprises several molecular simulations designed to enable instructors to teach chemistry using the perspective of emergent phenomena. That is, it allows students to see observed macro-level chemical phenomena, like many other scientific phenomena, as resultant from the interactions of many individual agents on a micro-level. This perspective is especially appropriate to the study of chemistry where the interactions between multitudes of molecules on the atomic level give rise to the macro-level concepts that students study in the classroom. Connected Chemistry comprises molecular simulations embedded in the NetLogo modeling software (1). The collection contains several predesigned simulations of closed chemical systems to teach specific chemistry concepts. Currently, Connected Chemistry contains models for teaching Brønsted Lowry acid base theory, enzyme kinetics, radical polymerization, buffer chemistry, kinetics, chemical equilibrium, and crystallization. Instructors and students can individually tailor the predesigned simulations or generate new simulations as they are needed in the context of a particular lesson, classroom, or department.
